The shared physical examination is coming! "Internet+medical care" brings a new experience of medical treatment

  Xinhua News Agency, Beijing, September 16 th, New Media Specialist (Reporter Mao Weihao) You don’t have to wait in line at a big hospital, you can test the urine sample by taking out WeChat and sweeping it; You don’t need an old Chinese doctor to take a pulse, but you can diagnose your constitution by taking a photo at the eyeball … …

  With the Internet companies marching into the grassroots general clinics, refreshing medical treatment scenes are constantly emerging, or will completely change the medical treatment experience of Chinese people.

  On the 15th, in the newly opened "Penguin Doctor" general clinic in Chaoyang District, Beijing, a device about the size of an air purifier caught the attention of reporters. According to Wang Shirui, CEO of "Penguin Doctor", this is a self-service body fluid testing instrument, which was jointly developed by Tencent and Tsinghua University. At present, it can complete three tests, such as urine routine and ovulation period.

  How to carry out urine sample testing by self-service? The staff gave a demonstration on the spot. Open WeChat and scan the QR code, and the machine will "spit out" a test paper. After completing the collection of urine samples according to the instructions, send the test paper back to the self-service machine, and the urine test results will be sent to the WeChat terminal soon and synchronized to the "Penguin Doctor" clinic.

  In this clinic, there are many similar "new and unique" testing equipment. For example, the detection process of "eye image detector" is similar to that of vision test, but the physical examination report can show which of the nine constitutions of traditional Chinese medicine patients belong to and give suggestions on health management.

  "Reconstruct the medical service process, break up the clinic services, release the services that can be shared, and put them around users, so that users can see their physical health more conveniently. We will make these self-help inspection and testing items like shared KTV or even vending machines, and put them in places where users can touch them quickly, such as office buildings and shopping malls, so as to save time for patients and doctors and provide patients with more humanized and convenient medical services. " Wang Shirui said.

  It is understood that "Penguin Doctor" is a medical and health science and technology enterprise jointly established by Tencent, Jihui Capital, Medical Association and sequoia capital china. At present, the "Penguin Doctor" general clinic has landed in Beijing, Chengdu and Shenzhen, and will be put into operation one after another. Its service scope covers all common departments such as internal medicine, surgery, stomatology, rehabilitation medicine, psychological consultation, dermatology and physical examination.

  In addition to sharing tests, future general clinics will also share doctors. In the "Penguin Doctor" clinic, it is not a full-time doctor who provides services to patients, but a part-time doctor who practices more. Patients must make an appointment in advance to see a doctor, so as to alleviate the shortage of doctor resources and improve the efficiency of doctor service.

  In addition, "Penguin Doctor" also connects more general clinics through cloud services to provide standardized services for patients. The data shows that the system has been online for only two months, and more than 800 offline clinics have been connected, and about 200 clinics log in and use the system every day.

Academician Chongqing Tour | Academician david moses of China Academy of Sciences: The Internet of Things is moving from "the Internet of Everything" to "the Internet of Everything"

"With the development of the Internet of Things, industrial ecological competition will become increasingly fierce." On the morning of July 27th, at the 20th anniversary of "Science and China" in Chongqing Science Popularization Report and the 6th Science and Technology Lecture Hall for Leading Cadres in Chongqing, david moses, an academician of China Academy of Sciences and an expert in the field of communication network, said that artificial intelligence was driving the Internet of Things, moving from "Internet of Everything" to "Intelligent Network of Everything".

Looking back at the "yesterday" of the development of the Internet of Things, david moses said that since the concept of the Internet of Things was put forward at the beginning of this century, it has been quickly recognized around the world and has become the core driving force of a new round of scientific and technological revolution and industrial transformation. "The Internet of Things industry is called the third wave of the development of the world information industry after computers and the Internet, which has profoundly changed the traditional industrial form and people’s lifestyle, spawned a large number of new technologies, new products and new models, and triggered a global wave of digital economy."
In China, in December 2018, the Central Economic Work Conference put forward the concept of new infrastructure for the first time, emphasizing the need to "accelerate the pace of 5G commercialization and strengthen the construction of new infrastructure such as artificial intelligence, industrial Internet and Internet of Things". David moses believes that the Internet of Things, as a highly integrated and comprehensive application of the new generation of information technology, is accelerating its transformation into real productive forces under the wave of new infrastructure, and has become the infrastructure and key element to reshape the mode of production organization and promote social development and progress.
Today, driven by the wave of new infrastructure, the development of China’s Internet of Things industry is ushered in a period of strategic opportunities. Focusing on the three application fields of supply side, demand side and smart city, the integrated application of Internet of Things and vertical industry is deepening, and the coverage scenarios are becoming wider and wider.
David moses, for example, said that the current application of the Internet of Things in the industrial field is mainly reflected in two aspects: networked sensors realize intelligent production. Through networked sensors, enterprises can dynamically perceive the status of production equipment, raw materials and personnel, realize intelligent decision-making and dynamic optimization of production process, significantly improve the production efficiency of the whole process, improve quality and reduce costs; Realize the transformation of enterprise service. Using the massive real-time data obtained by sensors, combined with the technologies of big data analysis and artificial intelligence on the cloud platform side, it provides services such as predictive maintenance and performance optimization to realize the service transformation of enterprises.
Referring to the future development, david moses said that while the new infrastructure will bring development opportunities to the Internet of Things industry, the industrial ecological competition will become increasingly fierce, which will bring many challenges. First, the core basic ability is still weak, and the industrial ecological competitiveness is insufficient. Second, there is a lack of integration and the guidance of leading enterprises, and the industrial chain is not cooperative. Third, the relevant standard system is still not perfect. Fourth, the integration of the Internet of Things and the industry needs to be further deepened. Fifth, the form of network and information security is still grim.
How to seize opportunities and meet challenges? David moses pointed out that it is the key to build a sustainable Internet of Things+new industrial system around the supply side and demand side, and to drive the coordinated development of the Internet of Things industry. "We must simultaneously promote the Internet of Things network construction, strengthen the research on Internet of Things standards and technologies, enhance the breadth and depth of Internet of Things applications, build a high-quality industrial development system, and establish and improve the Internet of Things security system to promote the comprehensive, healthy and rapid development of the Internet of Things industry."

The financial reporter’s movie "erin brockovich", watch the reporter bravely fight against the evil forces of capital!

For media people, this is a very special and important movie! Especially now!

Ye Daying’s new film "erin brockovich", which will be officially released on August 12th, tells the story of financial reporters cooperating with the judicial department to expose the evil forces in the capital market.

In erin brockovich, Yu Li, editor-in-chief of New Island Weekly, played by Dani, withstood the pressure from all sides and fought bravely with the evil forces. In the film, Yu Li was not only kidnapped, but also threatened with her life. Her assistant was lured by capital and defected. You Yongzhi, an old opera player, plays Wang Mingguang, the president of Yu Li’s newspaper. With his superb acting skills, he fights with the villains Hai Yitian and Wang Ce, which not only restores the capital fraud case brilliantly, but also shows the determination and belief of media people in upholding justice.

In addition to well-known actors playing important roles in the film, our old friend Li Delin, the founder of Delin Society & Standard Finance, a well-known financial reporter and co-founder of Deep Blue Finance, also played a certain role in the film, which may be the place where we media people are curious.

This is not just a movie, it can be regarded as a textbook for financial news and financial fraud investigation and reporting, as a horn to encourage financial media people to forge ahead, and as our professional mission to revisit. At the same time, this film is also an important reference for listed companies, the most important participants in the capital market.

Liu Jipeng, Dean of the Institute of Capital Finance of China University of Political Science and Law, talks about the impression of erin brockovich.

On the afternoon of August 6th, at the invitation of Wang Boming, Director-General of China Securities Market Research and Design Center and President of Finance and Economics Magazine, I watched the first China media people’s film erin brockovich, which will be released nationwide on August 12th, with He Qiang, Lin Yixiang, Yao Zhenshan, Chen Xingdong and Shen Yi.

Based on the true story of the kidnapping of Yu Ying, the female editor-in-chief of "Weekly Stock Market" in 2008 in the North Third Ring Road, this film records the tortuous process of media people bravely exposing the shady story during the listing of radish chapter of a securities company, and it can also remind people of the shadows of financial tycoons such as tomorrow, Anbang and Yongjin.

After nearly three years of review, it is not easy for this film to be finally released in such a big year as 2022. The title of the film has also been changed from "The Gate of the Predator" to "erin brockovich", which shows the joys and sorrows of the struggle between media people and financial predators in China stock market. It shows that China media people are indispensable as the second supervisory force of the capital market.

After watching the movie, a symposium was held, and the experts at the meeting talked about their views enthusiastically and deeply thought about the reasons behind why the China stock market has been in a downturn for 33 years. I deeply feel that today’s supervision of China’s securities market must be adjusted from focusing on beauty pageants and neglecting thieves to focusing on thieves and neglecting beauty pageants. At the same time, we should give full play to and protect the just power of media people to expose the shady.

An anonymous person in the financial circle talks about the impressions of erin brockovich.

This afternoon, I was invited to watch the film "erin brockovich" by the famous director Ye Daying (the director of the famous film "Red Cherry") and Wang Boming, the president of Caijing magazine, as the producer. The film fully reflected the efforts of a group of media people with ideals to defend the justice of the capital market with the support of judicial justice. After watching the film, I had a discussion with Liu Jipeng, He Qiang, Wang Wei, Lin Yixiang, Chen Xingdong and Shen Yi, famous economists and participants in the construction of the capital market for more than 30 years, and famous media people such as Wang Boming, Yu Ying, He Gang and Yao Zhenshan, director Li Bing of the State Council State-owned Assets Supervision and Administration Commission, Wang Hang, vice chairman of New Hope Group, and Li Jiang, a famous lawyer.

At the invitation of Dean Liu Jipeng, I talked about three experiences: First, we personally participated (I published a book on the reform of the shareholding system in enterprises in the first half of 1992, and in 1997 I served as the director of the A-share office of Sanjiu Group, obtained the listing index and planned the listing of related businesses of the Group; Later, he was the deputy head and office director of the Group’s financial decision-making leading group, coordinating the information disclosure and reorganization of three A-share listed companies such as Sanjiu Medicine) and witnessed the magnificent capital market in China for more than 30 years. The capital market is the product of reform and opening up, and has also made outstanding contributions to the reform and opening up, especially the reform of state-owned enterprises and the development and growth of private enterprises. At the same time, it also witnessed the standardized development of China’s securities market, gained a firm foothold in many major events, and persisted in implementing the Company Law and the Governance Standards for Listed Companies. The second is to thank President Wang and Director Ye for making a good film. After human beings have owned the capital market, illegal phenomena appear from time to time in the market. Criminals take the opportunity to make fakes, disrupt the market and infringe on the interests of listed companies’ investors. Therefore, in the past hundred years, the regulatory authorities of various countries have been constantly fighting against the violation of laws and regulations in the capital market. Many of them are regarded as the second supervisory force, pursuing the truth, safeguarding market justice and fairness and giving confidence to market participants. This is something we must support and praise. Third, China’s economic transformation and development, especially to break through the’ stuck’ technology and promote the rapid development of high-tech industries, need a strong capital market.A country’s fund-raising ability is an important part of the country’s comprehensive national strength. Therefore, while constantly standardizing and improving the capital market supervision system, promoting the efficient development of the capital market is the key to ensuring the strategic initiative of big countries in the future, and it is also our desire to expect the capital market to grow and develop.

Today, some old friends in the financial sector meet to recall the’ exciting’ reforms in full swing in the 1980s and the thrilling development of the securities market for more than 30 years, hoping for better development in the future. Thanks to the photo provider.

The effect of policy "combination boxing" appeared in the first three quarters, and China’s consumer market accelerated to pick up.

  Original title: Increased activity in the consumer market

  In the first three quarters, China’s consumer market accelerated its recovery. Among them, the total retail sales of social consumer goods increased by 6.8% year-on-year, the retail sales of services increased by 18.9%, and the contribution rate of final consumption expenditure to economic growth was 83.2%.

  Sheng Laiyun, deputy director of the National Bureau of Statistics, said that under the influence of a series of policies to promote consumption, China’s consumption, especially service consumption, showed a good trend of rebound and recovery.

  The market is recovering well.

  In order to promote the sustained recovery of the consumer market, since the beginning of this year, a series of policies and measures to promote consumption have been introduced from the central government to the local government, covering many fields such as automobiles and home furnishing.

  "As the effect of the policy’ combination boxing’ continues to emerge, the consumption of residents has improved, especially the consumption of some bulk commodities has improved significantly." Zou Xianyu, deputy director of the Macro Department of the Economic Forecasting Department of the National Information Center, said that from the overall trend, the cumulative growth rate of total retail sales of consumer goods in the first three quarters reached 6.8%, a significant increase of 6.1 percentage points over the same period of last year. In September, the total retail sales of social consumer goods increased by 5.5% year-on-year, 0.9 percentage points faster than last month, among which urban consumption accelerated by 1 percentage point in September, and the improvement trend of consumption growth momentum was further revealed.

  The recovery growth of domestic demand has played an important role in the stabilization and recovery of China’s economy. In terms of classification, residents’ consumption expenditure has accelerated, service consumption such as catering and accommodation has grown rapidly, and consumption of bulk commodities such as automobiles has grown steadily, and the potential of the domestic big market is constantly being released.

  Service consumption is a bright spot. Since the economic operation has returned to normal, the offline passenger flow has gradually picked up, driving the service consumption to recover quickly. The data shows that the year-on-year growth rate of service retail sales in the first three quarters was significantly higher than the growth rate of total retail sales of consumer goods. Xia Jiechang, vice president of the Institute of Finance and Economics of China Academy of Social Sciences, believes that in the consumer market, the development potential of service consumption is the most worthy of attention. Service retail not only has the general function of retail circulation activities, but also shows important driving effects in supply upgrading, consumption expansion, industry innovation and social employment, and is expected to become the new engine of China’s economic growth in the future.

  This year’s Mid-Autumn Festival and National Day holidays, whether it is the number of trips, tourism consumption or accommodation, catering income data, have maintained a strong growth momentum. "This shows that the market activity has increased and it also highlights the potential and vitality of market consumption." Sheng Laiyun said.

  While offline passenger traffic gradually picked up, online retail also maintained rapid growth. In the first three quarters, the national online retail sales reached 10.8 trillion yuan, an increase of 11.6%, which was 4.8 percentage points higher than the growth rate of the total retail sales of social consumer goods, and the contribution rate of physical network zero to social zero growth reached 33.9%. Among them, new formats such as live e-commerce are developing strongly. According to the latest data from the Ministry of Commerce, in the first three quarters, 151 of the 170 national e-commerce demonstration bases established live broadcast bases, and the national live broadcast e-commerce sales reached 1.98 trillion yuan, up 60.6%, accounting for 18.3% of the online retail sales. The live broadcast e-commerce pulled the net to zero growth rate of 7.7 percentage points.

  Consumption potential needs to be tapped

  Although the consumer market continues to recover steadily, the internal and external environment facing steady growth is still severe and complicated, and the consumption potential needs to be further tapped.

  Taking new energy vehicles as an example, the sales of new energy vehicles accounted for 29.8% of the total sales of new vehicles in the first three quarters, and the supporting charging infrastructure system was also continuously optimized. However, there are still some problems in rural areas, such as insufficient construction of public charging infrastructure, difficult installation and sharing of charging facilities in residential communities, and prominent contradiction between supply and demand in different periods, which restrict the release of consumption potential of new energy vehicles in rural areas. In the next step, we should effectively reduce the restrictions on the installation of charging piles in rural power grids, promote the popularization of rural charging facilities, and fill in the shortcomings of consumer infrastructure.

  In addition, it is necessary to strengthen the digital empowerment of traditional business districts and further promote the continuous improvement of physical store operations. Zou Xianyu said that in the process of focusing on supporting the construction of digital commercial blocks, it is necessary to support new business layouts such as smart retail, cross-border retail and unmanned supermarkets.

  "China’s consumption potential is relatively large, and its population size is relatively large. In addition, it is at a critical stage of upgrading its consumption structure. As the economy continues to recover, the overall consumption trend in China will be good." Sheng Laiyun said that in the fourth quarter, China’s consumption will continue to recover in the first three quarters.

  "Starting from the overall strategic situation, the state attaches great importance to expanding domestic demand in steady growth, gives priority to restoring and expanding consumption, and has launched a series of policy’ combination boxing’ to promote consumption." Wei Wang, a second-level researcher at the Institute of Market Economy of the State Council Development Research Center, said.

  At the same time, the overall employment situation has improved, and the income level has increased steadily, helping the consumption power to stabilize. In the first three quarters, the national per capita disposable income actually increased by 5.9%, 0.1 percentage point faster than that in the first half of the year, which laid a good foundation for the sustainable recovery and growth of consumption in the future.

  "Although the current economy is in the process of wave recovery and tortuous progress, with the continuous repair of the balance sheets of enterprises and residents, consumption willingness and consumption power are expected to further recover, and consumption momentum will be further enhanced." Zou Xianyu said that at the same time, we should also see that there is still a distance from the complete recovery of consumption, and the fluctuation of consumption growth is still large. From the perspective of key categories, the gap-filling effect of service consumption will end, and the whole will gradually return to the normal growth trend, and commodity consumption will maintain a moderate growth.

  Experts said that the current demand growth rate is still insufficient, and it is necessary to continuously enhance the confidence of enterprises and markets. At the same time, firmly grasp the key link of expanding domestic demand, accelerate the activation of the domestic market, and fully release the economic growth potential of China. (Reporter)

Us media: Ohio has begun to restore life order, but residents’ concerns are still difficult to eliminate.

After the toxic chemical spill, East Palestine, an industrial town in Ohio, tried to restore order. This week, schools in this area have resumed classes, restaurants have started serving meals, and trains have started running. However, residents of Palestinian towns are still worried about environmental pollution and safety.
On February 15, 2023, local time, in East Palestine, Ohio, USA, in East Palestine High School, local and surrounding residents lined up to attend the town hall meeting. Hundreds of worried residents of a village in Ohio gathered to ask officials questions about health hazards. Vision china According to a report by American media The New York Times on February 15th, in East Palestinian town, many residents are smelling the water from their faucets, looking in the mirror to check whether they have rashes, and are scared of dead fish and floating frog carcasses in the stream … Many people say that the smell in the air is lingering: some people think it is like the smell of burning tires, while others think of the smell of burning plastic, glue or nail polish remover.About two weeks ago, on February 3, a train carrying toxic chemicals derailed in East Palestinian town and caused a fire. After the accident, the East Palestinian town entered a state of emergency. On the 9th, residents were told that they could return to their homes. The New York Times said that after hundreds of residents were forced to leave the area for several days and returned to local life, their worries became the norm for many residents.
Long-term risks are worrying.
The train that caused the accident came from Norfolk Southern Company. According to CCTV news reported on the 16th, Norfolk Southern Company decided to carry out the so-called "controlled release" operation of vinyl chloride in five carriages on the 6th, which led to the emergency evacuation of residents within several kilometers of Fiona Fang due to the threat of deadly gas. On the 9th, some residents had symptoms such as headache and nausea after returning to their homes. The US Environmental Protection Agency said on the 13th that after the completion of the "controlled release" operation, the test results showed that the toxins associated with derailment events in the atmospheric environment had not reached a worrying level.
CNN)2 reported on February 15th that although residents of East Palestinian town have been home for about a week, people still prefer to buy bottled water rather than tap water. Ohio Governor Dwayne told CNN that the first test results of local water quality were "very good", but he also hoped that residents would not "risk" drinking.
On February 15, 2023, local time, Becky Rance and Waddle Colley in Ohio, USA distributed bottled water while continuing to clean up some sections of the freight train derailed in southern Norfolk a week ago. The East Palestinian town of vision china, with a population of nearly 5,000, is deeply anxious: the derailment of the train has had an unbearable impact on the local water, air, soil and surface. According to CNN, the US Environmental Protection Agency said that the dangerous substances on the derailed train on February 3 included vinyl chloride, ethylene glycol monobutyl ether, ethyl hexyl acrylate, isobutylene and butyl acrylate.According to the US Environmental Protection Agency and the US Centers for Disease Control and Prevention, the vinyl chloride that caused the fire may be decomposed into compounds including hydrogen chloride and phosgene, a chemical weapon used as a asphyxiant during World War I.. Maria Doa from the Environmental Protection Foundation told CNN that vinyl chloride is a volatile organic compound (VOC), which is the most toxic chemical substance in this derailment. This substance may cause cancer, liver damage and brain damage.
CNN pointed out that although recent monitoring by US authorities and Norfolk Southern Company showed that local substances such as vinyl chloride, hydrogen chloride, carbon monoxide and phosgene did not exceed the standard, many residents complained that they had symptoms of headache.
On February 8, Kurt Kohler from the Emergency Response Office of Ohio Environmental Protection Agency said that it may take several years to clean up and monitor the derailment accident site. Kohler promised that the Ohio environmental protection department will participate in the clean-up process for a long time. The environmental protection department at the federal level in the United States also stressed that they will "do their best to help protect the community (East Palestinian town)".
On February 15th, Norfolk Southern Company said that it was preparing to set up a charity fund with 1 million US dollars (about 6.84 million yuan) to support the East Palestinian town and help the local "recovery and prosperity". However, for the local people, these comforts are probably insignificant. The long-term risk of this accident is still unclear, and the environmental officials of the authorities have just begun to assess the long-term risk, which is worrying. Under such circumstances, it is difficult for businessmen to make new investments in East Palestinian towns.
How many unknowns are there?
Bruce Vanderhoff, Ohio Health Director, said that volatile organic compounds can "cause common symptoms such as headache, eye irritation and nose irritation at low levels". Vanderhoff said that all the data they have collected so far show that the content of these substances in the local air is very low, and the statement about residents’ headaches and animal deaths is "anecdote". James lee, spokesman of Ohio Environmental Protection Agency, told CNN on 15th that the smell of some toxic substances is obvious, which does not mean that the concentration of pollutants has reached harmful levels.
According to The New York Times, it is difficult for residents in East Palestinian towns to know how many things have not been revealed, which may be the most terrible thing for them. Residents of East Palestinian towns are not sure whether some dangerous factors that seem to be solved in the short term will pose a threat again in the next few years.
Some experts stressed that only a more comprehensive investigation can make the cause and consequences of the accident clear. The New York Times said that the information provided by the local government and railways confused the local residents, and the information was inconsistent, which weakened their trust. East Palestinian town used to be a prosperous industrial town, but the wave of factory closures for decades has hit the local area hard, and residents’ trust in public power is already very weak.
After the accident, rumors and conspiracy theories about derailment accidents were widely spread on social platforms such as Facebook and TikTok. In the local area, neighbors are also discussing and spreading these statements.
On the 15th, the East Palestinian town held an "information open day" on the derailment accident, but this did not ease the tension. Norfolk Southern Company did not participate in the meeting, saying that the accident made their employees increasingly threatened. Residents complained that the absence of the railway meeting made the so-called "open day" seem like a waste of time. Despite this, residents still lined up in front of the gymnasium where the "Information Open Day" was held.
A few days ago, residents of East Palestinian town realized that the derailed train carried more toxic chemicals than they thought, which made many residents think that more information was concealed by relevant parties.
"I just don’t trust anyone." Mike Routh, a 28-year-old local resident, told The New York Times. He lives in New Waterford, a small town five miles from East Palestinian town. A church in New Waterford has become an aid center for residents of East Palestinian towns.
Norfolk Southern Company offered to provide $1,000 in aid to local residents. Mike Rouse makes a living by installing cell phone towers. In the face of Norfolk Southern Company’s assistance plan, Rouse seemed hesitant, fearing that once he accepted this money, he would limit his lawsuit against Norfolk Southern Company in the future. Rouse said that Norfolk Southern Company would "buy out" his way out. "This is almost a war between greedy enterprises and American towns. This town has just begun to recover, and now it is going to die. "
The New York Times pointed out that at present, most of the anger is directed at Norfolk Southern Company. Some politicians also denounced the railway company. Ohio Governor Dwayne, a Republican, said it was "absurd" for Norfolk Southern Company not to inform local officials in advance of the substance on the derailed train on the grounds of "confidentiality".

The cooperation between Chinese and American universities has made a breakthrough in the study of fractional quantum anomalous Hall effect.

  Scientists in China have made important progress in the research related to quantum Hall effect.

  The research on quantum Hall effect in condensed matter physics has won three Nobel Prizes, one is the discovery of quantum Hall effect in two-dimensional electronic system, and the other is the discovery of fractional quantum Hall effect, both of which are phenomena under strong magnetic field. Another time was a theoretical discovery related to the quantum Hall effect.

  Publish a screenshot of the periodical web page. The pictures in this article are all provided by Shanghai Jiaotong University.

  Recently, the team of Li Tingxin and Liu Xiaoxue of Shanghai Jiaotong University discovered and verified the existence of fractional quantum anomalous Hall effect under the condition of zero magnetic field. The results were published in the famous journal Physics Review X in the field of physics research and were highly recommended.

  According to Shanghai Jiaotong University, this achievement has made a breakthrough in this field, and the team paved the way for a series of follow-up studies through the original preparation method of new devices. This study opens the door to the study of novel physical properties such as fractional charge excitation and anyon statistics under zero magnetic field, and provides new possibilities and opportunities for topological quantum computing and other research.

  Past lives of Hall Effect

  When Edwin Hall, an American scientist, studied the conductive mechanism of metals in 1879, he found that when a current and a magnetic field perpendicular to the direction of the current were applied to a conductor, the trajectory of electrons in the conductor would be deflected due to Lorentz force, which would generate a voltage across the conductor perpendicular to the direction of the current and the magnetic field, which was called Hall voltage, and this effect was called Hall effect. According to the principle of Hall effect, Hall sensor has been widely used in speed sensing.

  At the beginning of 1980, when studying the Hall resistance of two-dimensional electronic system, German physicist K. von Klitzing found that under the extreme conditions of extremely low temperature and strong magnetic field, the Hall resistance of the sample appeared a series of quantized platforms, and the longitudinal resistance would show zero resistance state accordingly. This phenomenon is called integer quantum Hall effect.

  Later, theoretical physicists realized that the concept of topology must be introduced into physical research by using the topology theory in mathematics, so as to fully understand the integer quantum Hall effect, thus opening the era of topological physics research. Integer quantum Hall effect has also become the first topological quantum state of matter discovered by human beings.

  Generally, electrons in vacuum always have an integer number of charges, so it is impossible to have a fractional charge. Li Tingxin, an associate professor at the School of Physics and Astronomy of Shanghai Jiaotong University, said, for example, that in the fractional quantum Hall effect that was surprisingly discovered later, an electron seemed to be split into three parts, each with a charge of 1/3. It can be said that the fractional quantum Hall effect is a strongly correlated quantum state of matter, which is essentially different from the integer quantum Hall effect. It is a strange quantum fluid and has become one of the important candidates for topological quantum computing.

  However, if there is a normal effect, there may be an abnormal effect. In 1988, American theoretical physicist D. Haldane calculated that the integer quantum Hall effect under zero magnetic field could appear, which was later called the quantum anomalous Hall effect. This theoretical work is also one of his representative works that won the 2016 Nobel Prize in Physics. So far, the quantum Hall effect has won three Nobel Prizes.

  Direct observation of fractional quantum anomalous Hall effect in rotation angle MoTe2

  In recent years, based on the two-dimensional material Moire superlattice system, researchers at home and abroad have carried out a lot of theoretical and experimental research on fractional quantum anomalous Hall effect, and finally focused on the corner MoTe2 system. From April to May this year, the research team of Xiaodong Xu of Washington University and the research team of Kin Fai Mak and Jie Shan of Cornell University in the United States independently reported the signs of fractional quantum anomalous Hall states in corner MoTe2. However, optical measurement methods are generally difficult to give direct and conclusive evidence of the existence of fractional quantum anomalous Hall effect.

  Left: The measured Hall resistance of fractional quantum anomalous Hall effect in rotation angle MoTe2 varies with magnetic field;

  Right: The change of Hall conductance with the filling factor of Moire superlattice at zero magnetic field limit, and a clear quantized Hall conductance platform of integer (E 2/h) and fractional (E 2/3h) can be seen.

  Recently, the teams of Li Tingxin and Liu Xiaoxue of Shanghai Jiaotong University (experiment) cooperated with the team of Zhang Yang of the University of Tennessee (theory), and made a breakthrough in the study of fractional quantum anomalous Hall effect. They designed and fabricated a novel corner MoTe2 Moore superlattice device, and directly observed the conclusive evidence of the existence of fractional quantum anomalous Hall effect by conducting electrical transport experiments, which was one of two independent experimental work in the same period in the world (the other experimental work was completed by Xiaodong Xu research team of the University of Washington, USA).

  This work has been highly praised by the reviewers, which is considered as a breakthrough in the field, and the original new device preparation method paves the way for a series of subsequent studies around the fractional quantum anomalous Hall effect. This study opens the door to the study of novel physical properties such as fractional charge excitation and anyon statistics under the condition of zero magnetic field, and provides new possibilities and opportunities for topological quantum computing and other research. The paper was published in Physical Review X 13, 031037 (2023), and was recommended by the editor in the form of Featured in Physics.

Close-up of the peak of the National Day return trip: the largest toll station in China lights up "Xinghe", and the "trunk maternal love contest" is coming again.

Today (October 8) is the long last day of the Mid-Autumn Festival, and the national tour and visiting relatives are still on their way back. The upstream news combed the public reports and found that because this year’s National Day is an eight-day long holiday, the return traffic is more dispersed, and the first wave of return troops was ushered in as early as October 5-6. Specifically, in the early stage, the medium and long-distance return traffic flow is dominant, and in the later stage (especially today), the short-distance return traffic flow is dominant. What are the characteristics of the return trip of this year’s National Day holiday? How do local public security, transportation and other departments respond in an orderly manner? What are the hot topics on the Internet on the way back? Let’s take a look.

Hire 13 doctors from Korean universities? This college is a hot topic! South Korea fears becoming China’s "education factory"? There was a university that completed a one-semester doctoral program in

Following Shaoyang College, it was also revealed that xingtai university was suspected of importing "Dr. Su Cheng" in batches.

According to media reports, in February this year, xingtai university published a list of candidates to be hired in 2021, including 13 doctors from Korean universities. According to the list, some netizens found that these doctors were previously in-service teachers in xingtai university.

These doctors were previously in-service teachers in xingtai university

According to Xingtai Human Resources and Social Security Bureau, these 13 doctoral students graduated from Youshi University, jeonju university University and Yuanguang University respectively. Among them, one is majoring in cultural management, one in business administration, two in China, three in landscape architecture and six in education.

According to the client of the New Yellow River, the reporter compared the list of doctors to be hired in xingtai university in 2021, and found that in a paper published in 2020 entitled "Research on Education and Teaching of Fine Arts Courses for Preschool Children", the author column is Dai Moumou, and the author units are Youshi University and xingtai university, which are highly consistent with the information of Dai Moumou in the list of doctors to be hired in xingtai university.

In addition, in a theme report published in 2018 in official website, xingtai university, some information about Dai Moumou also appeared, showing that Dai Moumou was a teacher of xingtai university Academy of Fine Arts and Design. The reporter found out by searching the author of the paper and the names of the people associated with the news reports of the school.It is true that there are many doctors with the same name, but they cannot be confirmed as the same person..

More than half of the Korean doctors selected by the school graduated from Youshi University in Korea. According to the New Yellow River client, a brochure on the enrollment program for doctoral students of Yoshi University, released by official website, shenyang jianzhu university, was circulated on the Internet. According to the brief introduction, the academic system of the program is 2.5 years, and each study lasts for 2 months in winter and summer vacations, and it is taught in both Chinese and Korean. There is no requirement for entrance examination and Korean language proficiency. Students can obtain the doctoral degree certificate of the school after completing professional courses and defending their papers.

However, on the evening of 25th, this enrollment brochure could not be found in shenyang jianzhu university official website.

An intermediary said that the in-service doctor of Youshi University has a 2.5-year academic system.

According to Jiupai News, on July 22, a consulting agency of a Korean study abroad institution said that applying for on-the-job PhD at Youshi University in Korea is a 2.5-year academic system, with five semesters in total, and each semester lasts for two months in winter and summer vacations.

According to its introduction, it is quite easy to apply for Korea Youshi University, Jeonju University and Yuanguang University. "Because the school ranking is not high, it can only be said that it is in the top 100 in Korea."

The tuition and living expenses of Youshi are also relatively low. So many people apply to these schools. "The total cost is 200,000-220,000 yuan, including 2.5 years of tuition, language learning fees, class translation fees and agency fees of 6,000 yuan." He said.

It said that the requirement for applying to Korea Youshi University is to graduate from full-time undergraduate and master’s degree, with academic certificate and degree certificate. "The external application is for college teachers, but if we handle it, it is not a teacher. There is no requirement for the grade point of the postgraduate period. " In terms of language, you don’t need to take the IELTS TOEFL test, but you can get the Korean Level 4 certificate before you graduate from the doctor’s degree.

According to official website, the Chinese version of Yoshi University, the requirements of the university for foreign applicants applying for doctoral programs are that they should have a certificate of TORK level 3 or above, but they should have a certificate of TORK level 4 before graduation.

Korean media once reported the phenomenon that Korean college teachers went to China to study for a doctorate.

According to a report by China Newsweek in 2019, the information released by the Korean Ministry of Education shows that in 2018, there were 3,636 Korean students studying for doctoral degrees in South China, almost double the number of 1,906 in 2013, and most of them were teachers of China University with master’s degrees.

This phenomenon is most obvious in jeonju university. Quanzhou University pioneered in 2012 and signed a contract with the Education Department of Hebei, China Province. In 2013, Jeonju University opened a special class. In the first year, it recruited seven teachers from China University with only a master’s degree, and since then, it has maintained the scale of 7-8 teachers every year.

Yuanguang University, which belongs to Jeollabuk-do area with Jeonju University, is a large number of doctoral students in China. As of October 2018, more than 150 teachers from China University were studying for doctoral degrees.

According to CCTV Finance’s report in 2019, South Korea’s "East Asia Daily" published a book entitled "Dr. Crash in Studying in Korea,South Korea fears becoming China’s’ educational factory’ ".,It is mentioned that a Korean university can enroll China doctoral students and complete a semester course in 12 days.. Afterwards, the Embassy of China immediately negotiated with the Ministry of Education of South Korea on such issues, and the South Korean side immediately asked universities to strictly manage the university degree system, and the universities involved also stopped the project.

According to Tianmu News, the geographical area of South Korea is two-thirds of that of Shandong Province, and the total population in 2021 is 51.8 million, which is only half of that of Shandong Province. According to the Statistics of Foreign Students in Domestic Universities in 2021 released by official website, the Ministry of Education, there are 365 universities recruiting foreign students, among which 132 universities have doctoral students studying abroad, and most of them are private.Among them, in 2021 alone, the number of Korean doctors in China reached 8,821..

Shen Yi (pseudonym), a doctor studying in South Korea, told Tianmu news reporter that there are a large number of colleges and universities in South Korea with a small population, and enrollment is definitely tight. Such unknown colleges and universities that launch "customized water blogs" are facing bankruptcy and are forced to open for business because of their livelihood. According to his doctoral experience, in order to recruit students, the school even offered Chinese courses on the principle of easy graduation. "The doctoral supervisors of these institutions will release questions before the professional ability detection exam, and everyone can pass the exam after reviewing." Shen Yi said that his doctoral supervisor is particularly popular because he can speak Chinese. Among the 15 doctoral students, there are many on-the-job teachers in non-university institutions.

In this case, why should domestic universities introduce "crash doctors" in batches? Earlier, the dean of a second-level college in Shaoyang University said in an interview with the media: "This is no way, but it is really conducive to improving the proportion of doctoral degrees in the teaching staff, and it is helpful for upgrading to a university and applying for a master’s degree in the future."

According to "Basic Conditions for Examining and Applying for Degree Authorization (2020)" issued by the State Council Academic Degrees Committee, in addition to arts and sports colleges, the proportion of full-time teachers with doctoral degree is not less than 25%.

According to the Interim Provisions on the Establishment of Ordinary Undergraduate Schools promulgated by the Ministry of Education in 2006, the proportion of full-time teachers with postgraduate degrees in universities should generally reach more than 50%, and the proportion of full-time teachers with doctoral degrees should generally reach more than 20%.

Volvo’s new XC90 listed: half-moon drop 180,000/become the new discount king

Volvo’s new XC90, which was recently unveiled at the Chengdu Auto Show, has attracted a lot of public attention since its debut. No matter whether it is its tough and unique appearance or the luxurious Nordic interior style, this authentic Nordic model has its unique charm, which continues to attract everyone’s attention.

However, unexpectedly, In less than 10 days on the market, the discount margin of the new Volvo XC90 has reached about 150,000 – 180,000 range. If it is in consideration of market performance, it should not be such a large price reduction in such a short period of time. So what is the significance of its guide price 63.09-84 9,900 yuan.

However, no matter what the reason is, the new XC90 has earned enough attention by relying on this price reduction, and has also become the new discount king. Although Volvo is also considered a luxury brand, compared with the old German luxury cars such as Mercedes-Benz, BMW, and Audi, its own influence and brand appeal still have a big gap, and it is impossible to face it head-on. Volvo’s usual approach is to use price cuts to attract consumers, which is also its usual marketing strategy. So it is not surprising that the new XC90 has slashed prices this time.

This new car cannot be counted as a new XC90, because only a small upgrade of the body interior and configuration is carried out, this is a mid-term model. In terms of the appearance of the new car, it retains the unique solemnity and stability of Volvo, giving people a strong sense of security. In terms of interior design, it showcases the luxury and comfort of the Nordic style. The new model’s interior has a stronger sense of technology than the old model, which is also a highlight. It is important to know that Volvo’s interior design level can be said to be a whole era behind.

For Volvo’s decline of about 150,000, it can also be seen as its return to its own level of price. People are more inclined to think that, The previous exorbitant pricing was just to demonstrate the toughness of the Volvo brand, and then huge price cuts were made as part of its marketing strategy. In any case, Volvo’s purpose has been achieved, and the effect is considered good.

What will happen to palm oil production? How does the reduction of palm oil production affect the global edible oil supply?

Palm oil, as one of the most important edible oils in the world, its output fluctuation has a profound impact on the global edible oil market. The reduction of palm oil production will not only affect the economy of producing countries, but also have a chain reaction to the global edible oil supply chain. In this paper, the main factors leading to palm oil production reduction will be discussed in depth, and how these factors affect the global edible oil supply will be analyzed.

Climate change and natural disasters

Climate change is an important factor leading to palm oil production reduction. Palm trees are very sensitive to climatic conditions, especially the changes of rainfall and temperature. Extreme weather events such as drought, flood and tropical storm will directly damage the growth of palm trees and lead to a decline in production. For example, Indonesia and Malaysia, as the world’s largest palm oil producers, are often affected by El Niñ o and La Niñ a phenomena, which will lead to changes in rainfall patterns, thus affecting palm oil production.

Outbreak of pests and diseases

Palm trees are vulnerable to various diseases and insect pests, such as red palm weevil and leaf blight. These diseases and insect pests will destroy the health of palm trees, resulting in their failure to grow and bear fruit normally. Especially in large-scale plantations, the outbreak of pests and diseases may spread rapidly, resulting in large-scale production reduction.

Reduction of planting area

With the enhancement of environmental awareness, some countries began to limit the planting area of palm oil to protect forests and biodiversity. For example, Indonesia and Malaysia have implemented many policies to restrict palm cultivation in virgin forests and peatlands. Although the implementation of these policies is beneficial to environmental protection, it also directly leads to the reduction of palm oil planting area, which in turn affects the output.

labour shortage

Planting and harvesting palm oil requires a lot of labor. However, with the rising labor costs and the declining interest of the younger generation in agricultural work, many plantations are facing the problem of labor shortage. The shortage of labor force will lead to the decline of planting and harvesting efficiency, which will affect the output of palm oil.

Effect of palm oil production reduction on global edible oil supply

The reduction of palm oil production will directly affect the supply and price of global edible oil market. Because palm oil plays an important role in the global edible oil market, its production reduction will lead to tight market supply and rising prices. The following are the main impacts of palm oil production reduction on global edible oil supply:

influencing factor Specific impact rise in price The reduction of palm oil production will lead to tight market supply and rising prices, which will further affect the costs of consumers and food processing enterprises. Increased demand for substitutes With the rising price of palm oil, consumers and food processing enterprises may turn to other edible oils, such as soybean oil and rapeseed oil, which will increase the demand for these substitutes. Supply chain adjustment The reduction of palm oil production will prompt the supply chain to adjust, including increasing the production and import of other edible oils to meet market demand.

To sum up, there are various reasons for palm oil production reduction, including climate change, pests and diseases, reduced planting area and labor shortage. These factors will not only affect the production of palm oil, but also have a profound impact on the global edible oil market. Understanding these factors and their effects is very important for investors, producers and consumers.
